SCHEDULE OF AIRWORTHINESS DIRECTIVES
De Havilland DHC-1 (Chipmunk) Series Aeroplanes
AD/DHC-1/3 Fuel Line Cock to Filter - Replacement 6/55
Applicability: All English production models. Document: 1. DH Chipmunk Mod. H.188; or
2. ANO 105.1.14.15.5.3.
Compliance: Forthwith.
Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to establish and maintain safety standards within the Australian civil aviation sector. These regulations were introduced to address the need for a comprehensive and enforceable set of rules governing aircraft operations, maintenance, and airworthiness. In addressing specific aircraft types and their operational safety, CASA issued various airworthiness directives (ADs) to ensure ongoing compliance with safety standards. For example, AD/DHC-1/3 pertains to the replacement of the fuel line cock to filter in De Havilland DHC-1 (Chipmunk) series aeroplanes. This directive applies to all English production models and mandates compliance forthwith to mitigate potential safety risks associated with the specified component. The overarching policy objective of these regulations and directives is to ensure the highest level of safety in civil aviation operations.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, addresses the application of airworthiness directives for specific aircraft models, such as the de Havilland DHC-1 (Chipmunk) series aeroplanes. Specifically, AD/DHC-1/3 mandates the replacement of the fuel line cock to filter in all English production models, as detailed in the document referencing DH Chipmunk Mod. H.188 and ANO 105.1.14.15.5.3. Compliance with this directive is required forthwith, ensuring that any identified issues are addressed promptly to maintain the safety and airworthiness of these aircraft. The regulation applies nationally across the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority (CASA), which oversees compliance through regular inspections and enforcement actions. There are no stated exclusions or exemptions in this directive, meaning it applies uniformly to all specified models within the jurisdiction. Subordinate instruments may further elaborate on the implementation and compliance procedures, but the primary directive itself is clear in its requirement for immediate action.
Key Provisions
The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which governs the maintenance and operation of civil aircraft in Australia. One such directive, AD/DHC-1/3, pertains to the De Havilland DHC-1 (Chipmunk) Series Aeroplanes, focusing on the replacement of the fuel line cock to filter (sections 1 and 6/55). This directive applies to all English production models of the DHC-1 series, as detailed in documents such as the DH Chipmunk Model H.188 and ANO 105.1.14.15.5.3. Compliance with this directive is mandatory and must be achieved forthwith, indicating the urgency of the requirement (section 1).
Under the Civil Aviation Regulations, operators of the affected aircraft must adhere to the directive's stipulations, ensuring that the fuel line cock to filter is replaced according to the specified guidelines. This requirement is crucial for maintaining the airworthiness of the aircraft and ensuring the safety of all persons on board. Operators must ensure that the replacement is performed by authorised personnel and that the aircraft is grounded until the necessary modifications are completed. This obligation extends to all aircraft owners and operators who must verify that their aircraft meet the directive's standards before continuing operations (section 1).
Failure to comply with AD/DHC-1/3 can result in severe consequences, including potential safety risks and regulatory penalties. The Civil Aviation Regulations impose strict compliance measures, and non-compliance with airworthiness directives can lead to enforcement actions by CASA. Operators found in breach of these directives may face civil penalties, including fines, as well as potential criminal charges for endangering the safety of the aircraft and its occupants. The exact penalties are not specified in the directive but are outlined in broader aviation regulations, which can include significant financial penalties and imprisonment for serious breaches (section 6/55).
